Over-discharging (draining the battery below its safe voltage) can harm LiFePO4 cells. Here’s how to prevent it:
- Set a Low-Voltage Cutoff: Configure your system to disconnect the battery at around 2.5V per cell (or as per manufacturer specs).
- Monitor Battery Levels: Use a battery monitor to track state of charge (SOC) and avoid deep discharges.
- Recharge Promptly After Use: Don’t leave the battery at a low charge for long periods.
- Use a BMS with Protection: A good Battery Management System will prevent over-discharge automatically.
By following these steps, you’ll protect your battery from premature degradation.
